[Bf-cycles] GSoC - Spectral Rendering

[Gavin Howard]

     Matthew,
     That is a very good point. I must admit though, that I am a
person who doesn't care about long render times if it gives me a great
images, even on animations. I could see myself using it for
animations, but I am one in very few.
     God Bless,
     Gavin Howard
